Treatment of hydraulic fracturing flowback water components with O3 and O3/H2O2

Treatment of hydraulic fracturing flowback water components with O3 and O3/H2O2

In this study ozone (O3) and ozone with hydrogen peroxide advanced oxidation (O3/H2O2) were used to treat typical constituents of hydraulic fracturing wastewater.  The water contained guar gum (GG, a thickening agent) and glutaraldehyde (GLU, biocide).  Both treatment processes were successful in improving biodegradability of the components as expressed by the BOD/COD biodegradability ratio.

Leachate treatment with the Fenton’s Process

Leachate treatment with the Fenton’s Process

The goal of the study was to improve the UV transmittance of landfill leachate.  As wastewater treatment plants switch their disinfection process from chlorine to UV, they realize that landfill leachate interferes with the effectiveness of the disinfection process by blocking UV.  The Fenton’s Process achieved moderate improvement in UV transmittance, but generation of solids was considered prohibitive by the landfill.
